It may be worn out valve lifters that are inside the engine. If you have more than 6,000 miles on the oil, valve lifters could run noisier. Changing to a high mileage type of motor oil may quite down the valve lifters noise somewhat. Synthetic oil used during the summer months could make it noisier too. If you can hear the noise while driving the car, it is not normal. Upon acceleration, if it gets noisier, you will be needing a valve job in the not to distant future.

The VG30E engine has hydraulic valve lifters so there is no adjustment possible. You can try replacing the oil and filter, substituting one quart of ATF for one quart of oil. Let it go for 3,000 miles and do it again if necessary. If after the third time the tapping is still there, you will need to replace the hydraulic lifters.

Most likely what you are hearing is a slightly loose rocker arm clicking when it contacts the valve. Even when they are adjusted properly they can make some noise - depending on the condition of the engine oil and the temperature of the engine. You might look into having your valve clearance checked and adjusted. Change your oil if you haven't recently and you might consider running a heavier, synthetic oil - especially if you have more than maybe 30,000 miles on the engine.

Realistically, you should have the valve clearance checked/adjusted every 15,000 miles and you oil changed every 4,000-5,000 miles max for synthetic oils, less for conventional oils.

It sounds like hydraulic lifter noise. The lifters open and shut the valves and can be helped by using a good synthetic oil and frequent oil changes. Lash is the clearance between the valves and lifters.

It really a question about comfortability. Some folks change their oil(s) every 5000 miles (or more), some every 2500/3000 miles and some might do it as often as every 1000 miles. Depending upon the model year of your bike current H-D specifications recommend changing the engine oil, transmission fluid, and primary chain case oils every 5000 miles whether using conventional or synthetic fluids.

There's no tappets adjustment needed for this engine as they are hydraulic lifters. Try using 10w40 instead and see what happens or otherwise try using Moreys oil treatment with your current oil as it seems to me that the noise is more at startup and for a short period. Cheers.

There was a "Silent Recall" for this problem. Basically the heads, lifters, and cam are all replaced. I had this fixed under the recall on 1995 Pathfinder when it had 44,000 miles on it. Now it has 175,000 and has been had the cold engine noise since 145,000. The ticking is more irritating that it is harmful (Per my mechanic). I don't want to stick 1,000's of dollars into it anymore, tolerance is much cheaper.

The Castrol synthetic 5W20 oil may be too light for your car. None of the following three sources recommend 5W20 oil.
